Made two 10 gallon batches this past weekend, added rice hulls, adjust water to grain ratio and re ordered the sequence for the start of the recirculation. Worked like a dream...... thanks for your help.
Nobody mentioned mill gap - so I will You may be milling too fine. Recommended gap is 1.5-1.7mm. At this gap you should be left with some barley husks to aid in filtering. You need to be careful not to adjust the water/grist ratio too high.
